I looked at the callers of applyAlterTable(): loadTableMetadata() is called after alter*() + dropTableStats(), and createTable() only creates an "incomplete table", so the table will be reloaded before it is actually used. Because of this, my impression was that tables are always reloaded by design. -- To view, visit http://gerrit.cloudera.org:8080/10116 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I59a671ac29d352bd92ce40d5cb6662bb23f146b5 Gerrit-Change-Number: 10116 Gerrit-PatchSet: 12 Gerrit-Owner: Csaba Ringhofer <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: Csaba Ringhofer <[email protected]> Gerrit-Reviewer: Lars Volker <[email protected]> Gerrit-Reviewer: Zoltan Borok-Nagy <[email protected]> Gerrit-Comment-Date: Fri, 18 May 2018 15:43:01 +0000 Gerrit-HasComments: Yes
